Sensor specifications

An Electrocardiogram (ECG or EKG) is a representation of your heart’s electrical activity as it beats and pumps blood throughout your body. The heart, comprised of powerful muscles, exhibits electrical activity as it contracts and relaxes during the cardiac cycle due to the neuromuscular pace-making systems built into our biology. These small changes in electrical activity can be observed by attaching electrodes to the skin, and serves as a useful indicator of heart activity and health. While extensive diagnostics using ECG is still in the realm of hospital settings (with 12-lead electrodes distributed across the chest), this important signal can still be detected and recorded using much less obtrusive means like the sensors built into the seat of the Cava bidet. These sensors provide useful information to users, including current heart rate, heart-rate variability (HRV), and changes in heart rhythm. These metrics have been implicated in research as correlates to stress, exercise, and other relevant activities that provide you with insights into your health and physiology. The software being developed at Cava also leverages this ECG information to gain secondary measurements like Pulse Transit Time (PTT) that can further augment information about your circulatory system and identify any trends that may appear over time.

The photoplethysmogram (PPG) is an optically obtained signal that is typically used to detect blood volume changes in microvasculature - small blood vessels underneath the skin. This type of sensor operates on the basis of light transmission/reflectance and absorption, using a light-emitting diode (LED) that provides illumination and a detector that can precisely measure the amount of light passing through (or reflected from) the tissues within the body. Because the body’s tissues are normally perfused with blood, the blood volume within capillaries changes with each beat of the heart. The amount of light absorbed/reflected by this blood volume also changes with these microvariations and such changes can be detected by sensitive photodiodes to provide information about heart rate and blood flow. Using different wavelengths of light, the PPG can also monitor the oxygen saturation in the blood; oxygen-carrying hemoglobin absorbs light at different wavelengths than de-oxygenated hemoglobin, and the relative amounts of both compounds can be inferred by the light collected by the detector, which provides a measurement of oxygen saturation in the blood (SpO2). 

Besides these useful indicators of cardiovascular function, the PPG allows us to obtain two separate measurements of heart function. The electrocardiogram records electrical activity of the heart, which is a near-instantaneous indicator of the heartbeat, while the PPG records the physical movement of fluids within the blood vessels. This means that we can detect the precise moment when the heart contracts, and at what time the pumping action delivers the blood to the periphery. The delay between the heartbeat and perfusion of microvasculature is called the Pulse Transit Time (PTT), which can then be used to estimate the blood pressure, acute variations of blood pressure-related vasculature, and respiratory effort.

Bioimpedance is simply the measurement of the body’s resistance to a small current passed between two electrodes. Because the body is comprised of a combination of water, soft tissues, and skeletal material it is a heterogeneous conductor of electricity; observing the resistance of the combined body composition gives us insight into the relative proportions of the components that lie within. Though bioimpedance analysis (BIA) is quite variable person to person and highly dependent on the types and configurations of the electrode sensors used to collect the data, we are working to utilize machine-learning based personalization and leveraging continuous recordings of BioZ over time to increase the consistency and accuracy of these measurements compared to the laboratory gold standards of Dual-Energy X-ray Absorptiometry (DEXA) and Magnetic Resonance Imaging (MRI). By maintaining consistent recordings of BioZ over time, we will be able to use your personalized data to better estimate the Total Body Water (TBW) and fat mass in your unique physiology. Consistent recordings over time allows us to utilize time-dependent Bioimpedance Vector Analysis (BIVA) that can help to iron out the variations that may occur as a result of “one-shot” data collection that could be subject to confounds stemming from hydration levels or recent exercise. Cava plans to develop software that improves upon existing bioimpedance analyses, validated against reference measurements to bring accurate, consistent data to the home.

Cava utilizes an high-resolution image sensor that will obtain consistent, registered representations of stool that will serve as inputs to a sophisticated computer-vision system that will estimate excreta volume and classify excreta consistency to provide insights about GI and urine health. The fixed nature of the excreta sensors and the consistency of the image representations to be collected by our scanner implementation eases the training of ML models and computer-vision efforts to obtain consistent, accurate analysis of stool and urine. Because machine learning depends on the repeated exposure of common “features” of inputs to an artificial neural network, the consistent scanning offered by the Cava bidet is an ideal platform for registration, labelling, and classification of excreta into analytically useful categories.

Registration of stool images will be used to train a machine-learning classifier that will provide Bristol Stool Scale values, provide a record of bowel movements over time, and allow users to track their digestive health in a far more detailed way than previously available. In development, we are building computer-vision technologies to estimate the volume and density of stool such that an even more detailed representation of stool characteristics (volume, density) can be obtained. This data can then be utilized in concert with our software to identify trends and correlations to diet that can help users to keep track of their GI health in a consistent, unbiased manner. 

Colorimetry and computer-vision-based urine analysis also in development will provide insights into urine content that has the potential to yield information about hydration levels, total urine volume, and urine solutes that may be similarly tracked and recorded. The combination of the data provided by excreta will offer unprecedented insight into gut and urine health and allow this data to be accessible by all users of the Cava device

Piezo-electric load sensors placed in four locations of the Cava bidet will provide weight-sensing and weight-distribution measurements. Sufficiently sensitive load sensors will also enable the recording of ballistocardiograms (BCG), which measures the recoil-like physical force exerted by the heart as it pumps blood during the heartbeat. Such measures are directly correlated to overall blood pressure and will supplement the data estimated from PTT-based blood pressure measurements.

Surface temperature sensors will provide temperature information that will be leveraged to infer core body temperature and variations over time.

Because the Cava device is heavily instrumented and provides simultaneous recordings of multiple sources of physiological data, the signals obtained from multiple sensors serve to augment and supplement each other, helping to improve the reliability of the measurements taken and providing additional “features” as inputs to software technologies used to classify body phenomena. Cava will fully explore the potential of the multiple sensors embedded into the device and maximally leverage the data within to pursue even greater insight into our physiology.
